To all whom. t may concern.'

Be it known that l, Gironde l). MACNICHOL, a citizen of the United States of America, residing at Toledo, Lucas county7 Gino, have invented new and useful Glass vare-Forining Mechanisms, of which the following is a specification. V

This invention relates to handling heated ware, especially in connection with forming plastic material.

This invention has utility when embodied in glassware forming machines in the manufacture of vessels as bottles and vials.

The machine may be continuously' driven by the belt 1 shown in Fig. 1 as on the loose pulley f?. carried by the shaft 3. 1When this driving belt 1 is shifted to the fast pulley d, the shaft 3 is driven to actuate the worms 5, 6. rFhe worm 5 drives the worm wheel 7 on the shaft 8 (Figs. 1 and 5). Fast on the shaft 8 are the sprocket wheels 9 over which pass the sprocket chains or conveyers 10. rlhe shaft 8 is mounted in the bearings 11 carried by the main frame 12. At-the remote end of the frame 12 from the shaft 8 are bearings 11 carrying the shaft 13 upon which is mounted the sprocket wheels 14 over which pass the sprocket chains `10 having the roller flights 15 forming anti-friction ware holders.- The worm 6 drives the worm wheel. 1G on the shaft 17 (Figs. 1 and 5) which has the sprocket wheel 18 thereon driving sprocket chain 19 extending over the sprocket wheel 20 fast on the shaft 21. The slack in this sprocket chain is taken up by the idler. 22. This shaft 21 carries sprocket wheels 23 mounted in the bearings 2st carried by the frame 12. The bearings Q4 also carry adjustable bearing brackets 25 for the shaft 26 carrying a pair of sprocket wheels 23 similar to the pair of sprocket wheels 23 on the shaft 21. Over these sprocket wheels pass the sprocket chains 27 embodying the guide blocks 28 `(Fig. 8) through each of which is reciprocable a rectangular non-rotatable element 29 having roller 30 mounted on the pin 31 extending into the element 29 from the inner end of said element so that said roller 30 may freely rotate, as by contacting the end of a rotating blank, thereby taking retarding friction off said blank when the face of the roller 30 is moved thereagainst by the action ofthe member 29 through its guiding roller 32 coacting with the cams 33. The cams 33 iirst move the disks 30 into contacting relation. with the ends say or a rotating blank.

In the manufacture of vials, a cylindrical tubular section, ot glass may be put between the guide plates 34 to rest in an anti-friction holder 15 on each ot the conveyers 10 to be carried by said conveyers under the bars 35 (Fig. 10) which are adjustable in the brackets 36 and carry the yieldable contacting member or sott rubber 37 directly opposing the anti-friction holders 15 of the conveyors or sprocket chains 10. As the sprocket chains travel the blank or Vware contacting the rubber 37 is caused to rotate.

rlhe motor 38, (Fig. 1) through its belt 39 drives the fan 40 having duct 41 leading therefrom (Figs. 1, 5, 10) to the fluid discharge means 42 which have upwardly opening outlet slots` parallel with, the machine way or line of travel of the ware. Between these air dischargingpassages is mounted the burner 43 having a discharge slot upwardly directed and parallel with the slots 42. rlhe bolt 44 adjustably mounts the burner 43 as to the machine frame 12 so that vertical or lateral adjustment may be had.

This action or' the burner on the blank serves to heat the blank and this heating or production of hot ware is maintained local to the portion directly above the burner 43 by the actionv of the air blast 42 directed upward. The ware on each side of the heated portion thereby provides a cooling blanket on each side of the jet protecting` the moving parts of the holders 15 and conveyers 10 as well as the rubber contacting members 37.

As the blank becomes heated centrally, in order to avoid thickening the blank may be elongated by moving the sections transversely of their line ot travel as to tl e way in the machine. This is accomplished by the driving belt 45 driving the pulley 46 on the shaft 4'?V mounted in the bearings carried bythe trame 12. rfhe shaft 47 (Figs. 1, 5) has the oppositely disposed spiral gears 43 eoacting with the spiral pinions 49 on the shafts 50. These shafts 50 (Figs. 5,10, 11) carry the ware contacting rollers 51 which may also be o'l a yielding material to better' engage the ware, such lmaterial being rubber. rlhese rollers 51 rotate positively with the under portions moving out as shown in Fig. 11 so that in contactingrthe ware or blank such blanks are thrust against the disks 30 causing the rollers 32 of the elements 29 to bear against the cam portions 52 and thereby gradually elongate the weakened central. portion of the blank as said cam sections are adjusted to the desired pre-determined extent. The rollers 32 are then urged inwardly by the cam portions 53 (Fig. 5) which inward travel. is permitted by the idle rollers 54,

similar to the live rollers 51. As the blanks pass the rollers 51, 54, they rotate on their own axes as well as have transverse, actuation. Upon leaving the rollers 54 the blanks again are rotated by the pressure bar or contacting members 3T, and abut adjustable end guides 55.

The sheet air ets or liuid discharge means 42 extend to the region oi the rollers 51, 54. To provide a means tor counterzu'ting any heating olt these rollers as well as deterioration oli the rubber, the duct 5G il'roin the tan 40 conveys fluid to `the roller jacketing members 57 (Figs. 1, 5, il) which jacketing members 57 provide a continuous current ot air in the member closely adjze cent a side olf the rollers. These jacketing members 57 have l'luid discharge openings 5S upwardly directed, one on each side ot the plane of the burner, which serve as current inciting means not only to conline the heat of the burner but quickly remove sueh heat by upward current directly above the burner.

To contribute to the ease in preventingheat deterioration or overheating ot the moving parts of the mechanism, for the ware or machine parts adjacent said ware, l'luid circulating passages are provided, there being a water supply line 59 having duetsy 60 (Figs. 1, 10) in communication with the 'luid passages 61 adjustably supported with the bars 37 by the brackets 3G and extendingparallel with the way or line oi travel ot the conveyers. Outlet ducts G2 (Figs. 1 and 12) serves to carry away the heated water and thus complete the circulation et thel liquid through the machine.

The cams 63 (Fig. serve to withdraw the members 29 so that they are in position to be acted upon by the cams 33 when they repeat their circuit in the continuous travel in synchronism with the holders i5, there being a disk 30 directly registering with each ot said holders in its travel past the cams 33, 52, 53, G3.

This drawing apart ot the blanks during` the continued heating thereo'l ellicets :i separation oin the blank into two sections, and a rounding` oli or flowing oli said separated sections to a closed end lol-1n.

In the production ot bottles or vials it is desirable that the closed end or bottoni be flat in many instances. To care for this positively a bottomingdevice is introduced. Fast on the shaft 17 is the toothed wheel 64 (Figs. 1, 2, timed to have its teeth in synehronism with the ware holders 15. The lever G5 mounted on the itulcrunl (3G has pin G7 riding` on the teeth ot the wheel (llto rock said lever against the eounterweigllt (SS and thereby through the adjustable link 69 coacting with the arm 70 to rock the shaft 71 (Figs. 2, 3, 4). This shaft 7l is maintained against lateral movement as te Lineaire its 'bearings 72 by the collars 73 held 'by the set screws 74. Intermediate thesebearings 72 the shaft 71 has right and lett threaded portions 75 upon which are mounted the bushings 7 6 and as to which the yokes 77 are 4held by the set-screws 78. These yokes 77 carry the bottoining paddles or lplates 79 and :the yokes are held from rotation by the `pins 80 extending therethrough parallel with the shaft 71. As the shaft 71 iis rocked by the lever 65 from the wheel G41 the plates or paddles 79 simultaneously move apart and then quickly return to their' central or closed position. This quick separation movement is timed to occur just as "the -blank sections with the plastic bottoms are in position as to the bottoming elements 79 and there accordingly results a gentle pat of short duration in the outward movement which forces the closed end of the blank sections into a plane insuring a flat bottom for the article. The severed and completely bottomed blank sections now contact at their inner ends the central. dividing` member or adjustable split tongue 81 (Figs. 5, 12) which is heated by the burner 82 as controlled by the valve 88. The heating of this tongue 81 is graduated to permit a uniform cooling of the formed bottom of the vial. The valve 84 may regulate the burner 85 as to the burner 82 while the valve 86 may regulate the next burner section 85 for still less heating than the burners 85 and 82. This tongue member 81 gradually works the blank sections away from each other and during this travel the outer ends are heated by the long narrow burners 87 mounted on adjusting bolts 411. These burners 87 have their exhausttaken up by the 'dues 88 thereover and the heating action oi' these burners may be confined to .the end portion and kept away from the holder in supplement to the liquid circulating passage G1 by the fluid duct 89 conveying air from the fan 110 to the 'luid dis charging means 90 parallel with the conveyers 10. rllhe burners 87 may accordingly diverge to allow for the transverse travel of the blank sections as produced by the adjustable central bottoming member or tongue 81.. The fines 88 are removably mounted upon the machine by the angle tongues 91 engaging in the brackets 92 (Fig. 12).

F ast on the shalt 8 (Figa-1, 5) is the sprocket wheel 92 having the sprocket chain 98 driving the sprocket wheel 941 fast on the shaft By the slotted adjustment 96 the sprocket wheels 97 may be adjusted to carry the sprocket chains 98 having guide blocks 28 for the reciprocable members 29 having the transverse Vactuating rollers 82. The inward recessed end of the member 29 carries the spring 99 against which 'the bearing 100 is held by the pin 101 so that theeollar 102-` (Fig. 9) arid the centering blade 103 are. non-i."otatably held by the nonrotatable element 29. The heated outer ends et the blanks passing the burners 87 are brought to a `plastic state as the burners are adjusted by the valves 104;, 105, and the sprocket chains 98 passing over the sprocket wheels 100, 97, bring in synchronism the centering element 108 for each holder 15 so that each article of ware may have the centering element 108 properly lined up therewith and hold such article during the lip or neck forming operation. rlhe adjustment 96 permits this proper positioning of the centering means 108 as to the holders as does the similar adjustment of the sprocket wheels 28 to their shaft 20 for alining the relatively rotatable disks 80 as to the holders 15. l

The driving pulley 107 serves to drive the shaft 108 having the universal connection 109 with the shaft 110 connected to ae tuate the pulleys 111 carrying the belts 112 passing over the pulleys 118 having the bearing block 11d provided with the liquid chamber to which extends the water supply duct 115 and from which extends the water exhaust 110 (Fig. The adjusting nut 117 serves to take up tension of the belts 112. rl`hese belts have a yieldable facing as a contacting member, say of rubber. These belts are driven in the direction of ware travel so that the ware is readily brought thereunder when it approaches the belts and the speed is such that for this short duration of time a high rotative velocity vis given the ware and this rotative velocity occurs while the centering means 108 is in active position as also duringthe neck or neck and lip forming operation.

Mounted in the trame 12 adjacent the pulley 118 is the bracket 118 carrying the upper member 119 yieldably held by the springs 120 to movably carry the upper neck former 121 (Fig. 14) as a non-traveling 11.0 member, while the centering element 108 may pass therebelow with the blank. Upposing this upper neck forming` member 121' is a similar lower neck forming member 121 also held yieldably in position by spring 120 115 acting upon the lower hinged member 119. While this device oic Fig. 141 is adapted to handling the ware, the preferred lorm is that of the device oi"v Fig. 15 which shows the spring 120 yieldably holding` the hinged 120 member 119 against the collar 102 of" the centering blade 108 while the actual neck forming is accomplished by the single lower neck forming element 121 rigidly held in the hinged member 120 by the bolt 122, in `125 denite adjusted position. and stationary while the traveling ware passes along.

The centering elements are controlled by the adjustable cams 123 timed to coact with the rollers 82 to insert the bladed centering 130 elements 103 in` the blanks as the blanks approach the high speed rotating device or `belts 112. These centering elements are withdrawn by the positively directing ad- ,justable cam sections 124i so that the reciprocable elements 29 are in position for a repetition of this centering Vtravel in their next movement into alinement with the ware holder 15.

lVith the ware thus completed and having just been released from the high rotative speed the take olf device becomes effective. This device embodies a coil 125 upon a flexible stem 126 and extends adjacent the pulleys 111l to yieldingly engage the completed vials by opposing the holders 15. The vials in passing along under the spiral 125 are held to the carrier and delivered thereby to roll under the iexible tape 127 yieldingly held thereagainst by the springs 128 to pass the completed ware'to the chute 129. Notwithstanding high speed of rotation or rapid travel rate of the carrier, the vials are kept in position on the carrier `for regular travel therewith and discharge therefrom,

kavoiding breakage from shifting out oi' alinement.

In the operation of the machine a length of tube ot the desired dimension is placed between the relatively adjustable plates^3t Vthe distance apart of which may be varied by thesetting of the brackets in the main frame 12. This blank 130 (Fig. 16) is heated and elongated to produce the blank 131 (Fig. 17) which is the form of the blank as handled by the transverse actuating rollers 51. At this step the heating of the elongated blank 131 results in the produc- -tion of the blank sections 132 (Fig. 18)

which blank sections have the pointed closed inner ends. Continued heating of these ends by drawing them in closer to the burner i3 as effective by the adjustable cams 53 flows these inner ends to a more abrupt or approximately iiattened portion, blank sections 133, (Fig. 19). This flattening is completed by the bottoming device blades 79, producing the blank sections 1311 (Fig.

20). l/Vhile the formed bottom is being gradually cooled by the member 81 which is also transversely actuating the blanks as to lthe Way or moving them outward, there is heating of the outer ends of said blanks by the burners 87 to produce the blank sections 135 of Fig. 21: These blank sections which have been rotated up to this point solely by the opposing contacting member, l s pressure bar or transverse actuating rollers, are now speeded up by the belts 112 as the nonrotating centering blade 103 enters such` plastic end and its collar 102 abuts said end. This cares for the forming of the inside and to finish the vial 136 of Fig. 22.

the end of the vial opposing the bottom. Simultaneously with this action, the iixed or non-traveling neck former 121 of short longitudinal extent and upon one side only of the blank completes the groove or neck The completed vial is then delivered to the take oil device of Figs. 6 and 7 carried by the extension 13T trom the bearing 138 carrying the pulleys 111.

In the machine of this disclosure there is possible a high capacity for output by continuous operation in the production of Ware uniform in character. The various devices and mechanisms incorporated herein are relatively adjustable permitting the handling by this machine of blanks of different diameter and diil'erent length as well as of varying thicknesses, making possible with a single machine considerable range of utility in the production of ware el? different characters and sizes.
